The Micross 4Gb Hermetic Space Grade Spin Torque MRAM, is manufactured utilizing Avalanche Technologies magneto-resistive random-access memory. This MRAM device architecture is analogous to Flash technology with an SRAM compatible READ/WRITE interface, a Configuration Register with enhanced ECC functionality and a Page Mode feature for improved performance. Data is non-volatile with a near infinite endurance and best in class, non-volatile memory data retention.

Optimal Design
  • Smallest hermetic Rad-Hard MRAM package available
  • Spin-Torque Transfer technology MRAM is highly resistant to magnetic flux, mitigating the need for radiation shielding
  • Spin-Torque Transfer technology has near infinite endurance and data retention greater than 10 years
  • MRAM memory offers the fastest access time of non-volatile memories
  • Best power profile of all non-volatile memories
    • Standby current: 5.5mA; Active current: 90mA
Flexible Package Options
  • LGA, BGA, & CGA ceramic packages options available in 142 pad/solder-ball/Columns provides integration flexibility
  • Space grade processor based systems and FPGA boards
  • LEO, MEO, GEO, and HEO space missions
  • Satellites
  • Launch vehicles
  • Space systems and vehicles
  • Aerospace Systems

Key Features
    • 22nm pMTJ STT-MRAM (Perpendicular Magnetic Tunnel Junction)
    • Inherently Rad-Hard MRAM technology
    • Spin-Torque Persistent MRAM in a single, small footprint & low-profile package (LGA/BGA: 18mm x 20mm x 1.65mm) (CGA: 18mm x 20mm x 3.31mm)
